By default, the EAP/Omada Controller supports English language only. So when you print the Voucher code and hand it over to the customer, it’s in English as shown in the picture below.

Some customers may want to localize the language or customize the information on the Voucher Code. This document will introduce an easy and practical way to achieve this.

Steps

Run the EAP Controller first. This is a mandatory step.

Find the installation path of the EAP Controller, by default, it’s “C:\Program Files (x86)\TP-LINK”. And then go further to the path “C:\Program Files (x86)\TP-LINK\EAP Controller\work\com.tp-link.eap.web\webapp\WEB-INF\jsp\hotspot” and find the print.jsp file. This file defines the print operation of the Voucher Code, and we can change the info on the Voucher code by modifying this file.

Please open the print.jsp file with the notebook and then find the getStatus(voucher) function:

function getStatus(voucher) {

return "Valid for " + transferTime2(voucher.duration * 60);

}

Here we modify the function as below

function getStatus(voucher) {

return "VALID FOR" + transferTime2(voucher.duration * 60);

}

Then find the getType(voucher) function:

function getType(voucher) {

if (voucher.type == 0) {

return "with single use";

} else {

return "with " + voucher.quota + " online user(s)";

}

}

Here we modify the function as below

function getType(voucher) {

if (voucher.type == 0) {

return "WITH SINGLE USE";

} else {

return "WITH " + voucher.quota + " ONLINE USER(S)";

}

}

Save the changes and then print the Voucher codes, the effects are shown as follow:

Note: all the changes will be restored to the default after you restart the EAP/Omada Controller.
